#XdmDocument

Namespace: PhoenixmlDb.Xdm.Nodes

Represents an XML document root node in the XDM tree.

The document node is the root of every XDM document tree. Per the XDM specification, a document node's children can only be element, comment, and processing instruction nodes — text nodes at the document level are not permitted. Typically, a well-formed XML document has exactly one element child (the document element), plus optional comments and PIs.

Document URI: The XdmDocument.DocumentUri identifies the document and is used by functions like fn:document-uri() and fn:doc(). For documents loaded from the database, this is typically the storage URI; for parsed strings, it can be explicitly set.

Base URI: The document node's XdmNode.BaseUri defaults to the XdmDocument.DocumentUri when not explicitly set, providing the root base URI from which all descendant nodes inherit.

#Example

Accessing the document element:

XdmDocument doc = parseResult.Document;
if (doc.DocumentElement is NodeId elemId)
{
    var rootElement = (XdmElement)resolveNode(elemId);
    Console.WriteLine($"Root element: {rootElement.LocalName}");
}
